1. Keep power at idle, pull to the buffet and then limit load at Va
2. Apply full power, pull to buffet then power off at Va and hold limit load
3. Only apply full power if you know that you will not reach Va in a 90° pull out from 80kts and so will hit the tightest radius fastest without being load limited in at any point.
4. Do not apply any power because although the radius may be wider on the buffet initially the rate is slower which means you spend more time in the pull out without gravity negatively impacting lift required.

Still not convinced I'm afraid, although I am prepared to accept that for most G/A aircraft they will be similar. For your latest challenge don't forget option 5.

5. Deploy high lift devices and pull to limiting 'g' for said devices

Indeed we could split this into a couple of sub-options involving the use of power as per your original!
